(54) PROTON, NEUTRON, ELECTRON OR ELECTROMAGNETIC RADIATION IMAGING


(57) The invention provides a radiation imagining method and imager, the radiation imager comprising: a coded mask (11) that comprises a material that modulates the intensity of the incoming radiation and a plurality of mask aperture regions (18) that allow a higher transmission of the radiation relative to other portions of the coded mask (11), and that is configured to rotate; and at least one radiation sensor (10; 12; 13), wherein the imager is configured to make compressed sensing measurements including rotating the coded mask (11) and generating radiation image data from the compressed sensing measurements using a compressed sensing reconstruction algorithm. The invention also provides coded masks for such a radiation imager.
